Unified Analysis Workshop

The next Unified Analysis Workshop will be held in Paris, France during July 10-12, 2017.

This is the week following the IGS Workshop and like the IGS Workshop will be hosted by the Institut National de l’Information Géographique et Forestière (IGN) and held at the University of Paris-Diderot (15 rue Hélène Brion 75013 Paris).

As in the past, this is not an open workshop but attendance will be by invitation only. Each of the IAG Services, as well as GGOS, are asked to select about 5 to 6 experts to participate in the Workshop. It is hoped that the Analysis Coordinators will be one of the delegates from each Service. The Service Chairs and Central Bureau Directors are also welcome, of course, and do not count towards the limit of 5-6 experts from each Service.

By the end of December, please send to Richard Gross <richard.gross@jpl.nasa.gov>:</richard.gross@jpl.nasa.gov>

(1) List of Delegates to the Workshop from your Service (can be preliminary).

(2) Comments on the draft topics to be discussed at the Workshop (see below).

(3) Suggestions for Sessions within each topic and their Chairs.

(4) Any other remarks you may have.

We look forward to seeing you in Paris for the Unified Analysis Workshop!

Best regards,

Richard Gross

Chair, GGOS Science Panel

UNIFIED ANALYSIS WORKSHOP TOPICS

NB: This is a straw-man list of suggested topics

in order to start the discussion of the program.

It will change in response to your comments.

Not all of the topics listed here will necessarily

be discussed at the UAW. And some of the

suggested topics are included in order to

stimulate / re-invigorate activity in that area.

(1) Data and Products of Services

Technique biases and systematic errors

SLR range biases

GNSS antenna patterns

VLBI antenna deformation

Timing biases

Model improvements

Mean pole

Time variable gravity fields

Subdaily tides including S1/S2

(2) Combined Data and Products

At SINEX level

At observation level

Possible new combined products

Combined atmospheric products

(3) Reference Systems and Frames

Limitations of current approaches to frame determination

Joint TRF/CRF/EOP determination

Limitations of data and products used to determine frames

Geocenter, scale from GNSS, DORIS

Co-location of techniques in space

Inclusion of existing space co-location data

Unified height system

(4) Standards, Conventions, and Formats

Metadata

SINEX format extensions

Inclusion of radio source positions

Inclusion of loading parameters (VLBI)
